BACKGROUND: Inulin can be extracted from the non-edible chicory root and high purity fructose can be obtained from hydrolysis of inulin and used as a valuable platform molecule for further valorization. Heterogeneous catalysts are sought as alternatives to mineral acids because of costly separation and severe corrosion problems. In this work, hydrolysis of inulin was performed in a batch reactor with an advanced sulfonic resin (Smopex-101) employing HCl as a reference catalyst, at 75-95 ∘ C and pH ranging from 1 to 2.

“…Compared with acid hydrolysis, enzymatic hydrolysis has mild reaction, less by-products, no pigmentation, and is easier to separate and refine. Furthermore, the unique advantage of enzymatic method is that it can simultaneously combine hydrolysis and fermentation in Jerusalem artichoke biorefinery, which shorten the overall time and improve the productivity [ 27 ]. In addition, some microorganisms can directly produce inulinases to hydrolyze inulin and avoid the addition of enzymes during refining, which greatly reduces the cost [ 28 , 29 ].…”

The Jerusalem artichoke is a perennial plant that belongs to the sunflower family. As a non-grain crop, Jerusalem artichoke possesses a number of desirable characteristics that make it a valuable feedstock for biorefinery, such as inulin content, rapid growth, strong adaptability, and high yields. This review provides a comprehensive introduction to renewable Jerusalem artichoke-based biomass resources and recent advances in bio-based product conversion. Furthermore, we discuss the latest in the development of inulinase-producing microorganisms and enhanced inulin hydrolysis capacity of microbes by genetic engineering, which lead to a more cost-effective Jerusalem artichoke biorefinery. The review is aimed at promoting Jerusalem artichoke industry and new prospects for higher value-added production.

“…A fuzzy Analytic Hierarchy Process (AHP) is employed to prioritize the factors affecting the growth of artichoke, since it is a structured technique for organizing and analyzing complex decisions [14,15] . The focus of the presented study is on the therapeutic features of the plant in the treatment of liver diseases.…”

Today, the use of herbal medicine like artichoke is rapidly increasing worldwide. The consumption of artichoke as a food source is raising too. Therefore, it is necessary to determine the main factors affecting the growth of this plant which is investigated in this study. A comprehensive analysis of the literature is performed to detect these factors. A fuzzy Analytic Hierarchy Process (AHP) is employed to prioritize the factors. Results indicate that the conditions of irrigation and soil are the most important ones. In addition, the best conditions for artichoke growth are the medium level of irrigation, soil with suitable drainage, low temperature and sufficient sunlight.
